A.T. Robertson Commentary Acts 3:4

"And Peter, fastening his eyes upon him, with John, said, Look on us." — Acts 3:4 (ASV)

Fastening his eyes (ατενισας). First aorist (ingressive) active participle of ατενιζω. For this verb see on Lu 4:20; Acts 1:10. Peter fixed his eyes on the beggar and invited him to look (βλεψον) on them.
